There is no direct connection between the PMIC and the fusb302. Not in the driver, not in DT and not on the hardware. The fusb302_get_connector_node() function you are referencing is for the USB-C connector devicetree node. You can find it here: https://github.com/u-boot/u-boot/blob/master/arch/arm/dts/rk3588-rock-5b-u-boot.dtsi#L35 Greetings, -- Sebastian
